Beneficial effect of the present invention: portable bluetooth control device of the present invention can be realized mutual with smart machine, for smart machine increase can be by user-defined remote control function, for controlling smart machine; Control end circuit is positioned over convenience attractive in appearance in ornament; Device of the present invention is novel, design ingenious, convenient and practical, fashion attractive in appearance.
Accompanying drawing explanation
Fig. 1 is the control end electrical block diagram of the portable bluetooth control device of the embodiment of the present invention.
Fig. 2 is controlled terminal (smart machine) the workflow schematic diagram of the embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further elaborated.
Portable bluetooth control device of the present invention, specifically comprise control end circuit, control end electrical block diagram as shown in Figure 1, comprise: bluetooth serial ports module, processor unit, switch, current-limiting resistance R1 and pull-up resistor R2, wherein, switch is in normally open, one end lotus root of switch is connected to earth potential, the other end is connected with one end of pull-up resistor R2 and the input pin of processor unit, the TX pin of bluetooth serial ports module is connected with the RX pin of processor unit, the RX pin of bluetooth serial ports module is connected with the TX pin of processor unit, the VDD pin of bluetooth serial ports module, the VDD pin of processor unit is connected with input voltage through current-limiting resistance R1.
In the structure of Fig. 1, processor unit is specially 51 single-chip microcomputers, for the input voltage of its power supply is specially 3.3V.
For convenience attractive in appearance, the control device here also comprises ornament, and control end circuit is positioned in ornament.Ornament is specially brooch, button, job number board Kato or flexible paster.In concrete use procedure, flexible paster can be attached on vehicle steering or bicycle handlebar on hand.
The bluetooth serial ports module here utilizes antenna to send corresponding data to matching unit when receiving serial data; Single-chip microcomputer, is responsible for interpreting push button signalling, is construed to corresponding order and sends to bluetooth serial ports module.
According to the Main Function of portable bluetooth control device of the present invention, be by Bluetooth control smart machine (smart mobile phone).
Specific works process is as follows: control end circuit supply when operation, button is in normally open, now because the effect single-chip microcomputer input pin GPIO of pull-up resistor R2 is in high level; When pushing button, single-chip microcomputer input pin GPIO is communicated with ground, in low level, and by the program judgement button moving in single-chip microcomputer be short by or long by, if short, press, by serial ports TX, to bluetooth serial ports module, send " 0 ", make bluetooth serial ports module send data " 0 " by a day alignment matching unit; If long, press, single-chip microcomputer sends " 1 " by serial ports TX to bluetooth serial ports module, makes bluetooth serial ports module send data " 1 " by a day alignment matching unit.
Software workflow on smart machine (smart mobile phone) as shown in Figure 2.After software startup, search and Auto-matching bluetooth equipment, carry out circular wait blue-teeth data after matching bluetooth equipment.If the blue-teeth data receiving is " 0 ", enable refusing incoming call function, i.e. rejection current call, and send the note that content is " be inconvenient to answer the call, contact after a while with you " to the other side; If the blue-teeth data receiving is " 1 ", start searching mobile phone function, mobile phone is set to outdoor pattern, and plays music.
Software workflow on the specific implementation process of above-mentioned single-chip microcomputer and smart machine (smart mobile phone) can be considered prior art.
Contribution of the present invention is to provide a kind of portable bluetooth control device, pass through control device, by bluetooth, by existing ripe software module, realize and control smart machine (smart mobile phone), and then realization and smart machine is mutual, for smart machine increase can be by user-defined remote control function, for controlling smart machine; Control end circuit is positioned over convenience attractive in appearance in ornament; Device of the present invention is novel, design ingenious, convenient and practical, fashion attractive in appearance.
Those of ordinary skill in the art will appreciate that, embodiment described here is in order to help reader understanding's principle of the present invention, should be understood to that protection scope of the present invention is not limited to such special statement and embodiment.Those of ordinary skill in the art can make various other various concrete distortion and combinations that do not depart from essence of the present invention according to these technology enlightenments disclosed by the invention, and these distortion and combination are still in protection scope of the present invention.
